Mr Tyschtschenko worked for Commodore, ESCOM and in the Gateway days, then he retired. So why do you ask him about what happened afterwards? How is he supposed to know?
Gateway retained the patents, which if you asked about Amiga IP is what you'd be talking about. Trademarks lapse if you don't trade using them & who owns the copyright of the software has been debated in court as there is no documentation of a transfer.
Asking the wrong question is unlikely to get the answer you want.
What was it you wanted to know?
